16 Claims.

This invention relates to the hatch constructions of metal car roofs of the type wherein the hatch-ways are arranged in pairs one on each side of the roof and are defined by metal hatch frames that extend above the level thereof. The invention has for its principal object to increase the strength and rigidity of the roof between hatch frames and to brace and strengthen the portions of the hatch frames located above the general level of the roof. Other objects are to utilize the hatch frames as part of the roof covering, to increase the space available beneath the roof for insulation and to provide for simplicity and cheapness of construction and compactness of design. The invention consists in the hatch construction and in the parts and combinations and arrangements of parts hereinafter described and claimed.

In the construction shown in Figs. 1 to 7, inclusive, of the accompanying drawings, my in in Fig. 1,

vention is shown embodied in a railway car roof comprising metal roof sheets A that span from side plate B to side plate B of the car and have depending end or eaves flanges I that overhang and are riveted or otherwise rigidly secured flatwise to the outer sides of the upstanding inner flanges 2 of said side plates. These main or full length roof sheets A are connected along their adjacent side margins by rigid upstanding seams are riveted or otherwise secured to said flanges and are turned down over the depending eaves flanges l of said roof sheets and are riveted or otherwise rigidly secured thereto and to the upstanding flanges 2 of the side plates B.

Between adjacent roof seams C, the two full length roof sheets A are spaced apart to receive are spaced apart on opposite sides of the roof. These two hatch frames extend above and below the roof sheets A with their lower end portions supported in openings provided therefor in a framework comprising spaced carline members 5 connected by spaced cross-members 6, said members preferably comprising metal angle bars disposed with one of their flanges down to define the hatch frame receiving openings in said framework and with their other flanges facing outwardly in flush alinement to form a continuous supporting surface around each of said openings. The cross-members 6 have their ends Welded or otherwise secured, as at 'l, to the carline members 5. The hatch frames D are secured to the cross-members 6 by welds 8, which extend continuously along the lower edges thereof, and to the carline members 5 by spaced Welds 9 along hatch frames. The ends one leg welded, as at II, to the depending flanges of a carline member and the other leg riveted to the inner face of the upstanding flange 2 of a side plate. As shown in the drawings, the spaced apart margins of the full length roof sheets A are supported on the top flanges of the carline members 5 and are provided with upstanding edge flanges I2 that are disposed flush with the depending flanges of said member and extend from eaves to eaves of the roof and are turned down over the side plates with the depending eaves flanges I of said sheets.

As shown in the drawings, the space or opening defined by the upstanding side marginal flanges l2 of the spaced full length roof sheets A and the opposing sides of the spaced hatch frames D is covered by a ridge roof sheet E; and eaves sheets F cover the spaces or openings between said flanges from said hatch beams to the side plates B. The ridge sheet E has its body portion disposed above the general plane of the roof and has itsopposite side margins flanged downwardly to form depending side walls or flanges l3 and thence outwardly to form outstanding base flanges I l. The depending side walls l3 of this inverted channel-shaped ridge sheet E overhang and are riveted or otherwise rigidly secured to the upstanding flanges E2 of the sheets A, with the base flanges l4 seated on the body portion thereof. The ridge sheet E has upstanding end flanges I5 that are riveted or otherwise rigidly secured fiatwise to the opposing'sides of the hatch frames D, said flanges being further secured to said walls by continuous edge welds l6. At the corners of the hatch frames D, the side walls thereof are secured together by welds H, and the joints between thecorners of the ridge sheet E and the adjacent ridge corners of the hatch frames D are fllled with weld metal is. At their ends, the depending. side walls It of the ridge sheet E are secured'by edge welds I9 to the sides of. the upstanding side marginal flanges l2 of the full length roof sheets A. The eaves sheets F have depending eaves flanges which, like the depending eaves flanges I of the main sheets A, are riveted or otherwise rigidlyv secured to the upstanding, inner flanges 2. of the side plates B. Said eaves sheets also haveupstanding flanges 2i at their. inner ends that are riveted or otherwise secured flatwise to the. adjacent side walls of. the hatch frames. andare further secured thereto by edge welds 22. along the tops of. said last mentioned flanges. Said eaves sheets .alsohave up? standing side marginal flanges 23 that abut fiatwise against the flangesl2 of the sheets A and are turned .down with the eaves flanges 20 over the side plates. The abutting flanges l2. and 23 are rigidly secur-edtogether preferably bywelds along the flush upper edges thereof. 7 The upstanding flanges l2 of the full length sheets A are rivetedflatwise to the adjacent side walls of the metal hatch. frames Dand are also further securedthereto. by edge welds Eiextehding along the tops of said flanges.

7 By the arrangement described, the hatch frames D are sustained by the framework of.the carline members B-and crossmemberstlocated beiowthe roof and also by the flanged side marginslziof the full length roof sheets A that'are supported'on said'carline members and extend along and are rigidlysecured to two oppositewalls of each of'said hatch frames. The eaves sheets F arealso supported on the framework and are rigidly secured to the full length sheets A and to the side plate. B; and the 'roof sheets A, E and F all have rigid waterproof connections with the walls of the hatchfrarnes. The hatch frames. ex tend a considerable distance. above the roof, thus preventing water from splashing over the topsof said frame. The ridge sheet, being located above the general level of the roof serves as a combined strut and tie between the two hatch frames and thus stiffen and strengthen the upper'portions thereof against lateral shocks. At the same time, this higher elevation of the ridge sheet considerably increases the modulus of resistancelof the roof between hatch frames, thereby'increasing the vertical strength of the roof at the ridge. In the modification shown in Figs. 8 and 9, the eaves sheets are dispensed with'and the space between the "hatch'frame D} and the side plateB is covered by a lateral extension 26 of the outer side Wall of the hatch frame. The hatch frame ex tension 26 extends outwardly in conformity with the slope of the roof and terminates in a depending eaves flange 21 that is riveted or otherwise secured flatwise to the outer face of the upstanding inner flange 2 of the side plate B. As shown in Fig. 9, this roof covering extension 26 of the hatch frame is secured by an edge weld-28 to the adjacent sides of the carline members 5; and the flat side margins of the full length sheets A overlap the adjacent margins of said extension and are'secured thereto by edge welds 29.

In the construction shown in Figs. 10, 11 and 12, the invention is shown embodied in an insulated car roof; Inthis construction, the hatch frame supporting framework comprises carline membersfiai and cross connecting members 6a in the form of angle bars whose hatch opening defining flanges extend upwardly above the general level of the roof. As. shown in Fig. 10, the sides of the .hatchframe. that extend longitudinally of the roof are riveted or otherwise secured to the innerfaces of the upstanding inner flangesofthe cross frame membersfia. andare notched to accommodate the carline members 501.; and two remaining sidewalls of said hatch frame are made in upper and lower sections, the upper sectiontt being riveted-or otherwise secured to the outer faces of the upstanding flanges-0f said carline members andthe lower sectionsBl having their upper edges-welded or otherwise secured tothe lower inside corners of said carline members.

The eaves sheet F has its upstanding'inner flange 2i riveted'to theupstancling flange of the outermost cross frame member 6a; andthe ridgesheet E hasdepending side margiilal'flanges He that extend downwardly between theupstanding flanges of the carline members andthe upstanding flanges l2 of the full length sheets A, all of said flanges being riveted or otherwise rigidly secured together; The flanged'side margins l2'of the sheets A rest on the outstanding bottom flanges of the car1ines5a; andthe'ridge sheet has upstanding end: flanges l5a riveted and welded to the adjacent sides of the two hatch frames.
